AI Binocular Face, Palm Vein & QR Code Recognition Sensor

1. Getting Started

The article offers a detailed guide on installing AI vision modules, focusing on optimal installation heights, recommended tilt angles, cover plate materials, and proper assembly to prevent imaging issues and enhance performance.

2. Example Code for Arduino-Registering Face & Palm Print

When registering face or palm print, you need to fix the AI visual sensor and pay attention to the recognition distance, 30-120cm for face, 15cm for vein palm print, and 15cm for QR code. Only one face or palm print is registered each time. If you need to register multiple, you can press the reset button of the UNO R3 development board to register other faces or palm prints again.

3. Example Code for Arduino-Continuously Recognize Faces, Palm Prints, and QR Codes

Continuously identify faces, palm prints, and QR codes, and print the corresponding information through the serial port monitor. If it cannot be recognized, you can adjust the distance or posture slightly and keep it still.

4. Example Code for Arduino-User Statistics & Deletion

Input command: AT+GETUSERS, query all user numbers and IDs; AT+DELUSER=1, delete the specified user ID1, 1 can be replaced by other user IDs; AT+DELALLUSERS, delete all registered users.
